TA 403

General Information

TA 403 is a Polyoxypropylene-carbon atoms. Hence the nucleophilic reaction triamine with an average molecular weight of the amine groups is sterically hindered by about 400. The carbon-oxygene backbone is the vicinal methyl groups. This leads to a terminated on both ends by primary amine moderate reactivity of TA 403 groups which are attached to secondary which is desired for many epoxy applications.

Chemical and Physical Date

Properties	TA 403	Unit
Appearance	Colorless to yellowish liquid
Density at 25°C	0.98(61)	g/cm³ (lb/ft³)
Boiling point	>200 (>392)	°C(⁰F)
Water	0.2	% m/m
Primary amine content	>90	% m/m

Application

TA 403 is a highly reactive chain extender for polyurethanes and used as a modifier. Using of TA 403 in epoxy applications leads to extremely hard products which are resistant to impact stresses and thermal cycling.
